how do I write to a bank to issue a credit card for our employee guaranteeing and authorizing the bank to deduct the balance due on the credit card from our account with them, if he fails to pay the due balance within due date.

Sample

We would appreciate it if you could issue a credit card with the credit limit of Xxxx (amount in words) for Mr. XXXXX, XXXX Nationality holding ID number XXXX, issued at XXXX expiring on XX/XX/XX, working as XXXXX with our company.

We guarantee and authorize XXXX bank to deduct any due balance on the credit card from our account number XXXX with your Bank in case of his failure to pay the due amounts within the due dates.

Thank you for your kind cooperation.
